I dunno, but I'm curious why you want to run so many VMs' or zones? the database/mail/web stuff would probably all run most efficiently in the 'host' OS... I can see some advantages to running student interactive logins in a VM or zone for security isolation. its that, or I'd put the infrastructure things (email, school web, school databases) on a dedicated and secure hardware platform, then put all the instructional stuff on a seperate hardware platform. I don't like having too many eggs in one basket.
